WILLIAM it. BINGLEE, 0E PHI baht? 1J- ELPHIA, IPNSYLVAN INDEX TAB.

To all whom it my camera:

Be it known that l, WiLLIAM A. Rmcnnn, a citizen of the United States residing at Philadelphia, in the county of lhila'delphia and State. of Pennsylvania, have invented certain new and useful Improvements in Index Tabs, of whichthe ollowing is a full, clear, and exact description.

This invention relates to index cards, guides, sheets and the like, of the type which employ a tab of transparent material, such as celluloid, for supporting and displaying" a removable index sli or label and protecting theslip or label rom wear and soiling due to handling. An object of the invention is to provide a card, sheet, or, the like with an'improved permanently attached index tab of transparent material, by which the index sli or labelma be effectively pro tected and isplayed. further ob ect is to provide an improved transparent tab for attachment to sheets, cards and the like which will interchangeably receive and display suitable index slips or labels; which may be formed entirely of transparent material, such as celluloid; and which is comparatively rigid, durable, easily attached to cards and the like, and inex ensive. Other objects and advantages wi 1 be apparent from the following description of an embodiment of the invention and the novel features will be particularly ppinted In the accompanying drawing: 5 Fig. l is an elevation of an index cardv havin secured thereto a'tab constructed in acc'or ance with this invention;

Fig. 2 is a'section of the same taken substantially along the line 2-2 of Fig. 1; Fig. 3 is a plan of a sheet blank of transparent material from which the tab is formed;

Fig. 4 is a perspective of the sheet blank after it has been folded;

Fig. 5 is ajfront elevation of a card with the tab applied thereto in a slightly differout manner;

Fig. 6 is a. side elevation of the same; and I Fig. 7 is an end elevation of the embodiment of Figs. 1 and 2 when the ed e to which the tab is ap lied is folded ackwardly through a small an 1e so as to more effectively display the in carried thereby; v i

In Figs. 1, 2 and 7 the tab is shown as applied overthe usua index projection of ex slip or label the first fold and the edges opposite thereto,

so as to form between the folded edges 2 and 5 an open-ended pocket. A suitable cement 6 is then applied between the faces of the sheet which are brought together by the second folding operation, so as to secure the folded over pocket portion securely to one of the flaps of the tab. Any suit able cement may be used, but preferably a cement is used which contains-a solvent of the transparent material so that when the pocket portion is secured thereby to one of the flaps, it will be practically, if not actually, integral with the flap. The inner faces of the flaps from the folded edge 5 to the free edges opposite thereto are provided with a suitable adhesive or cement coating 7, and the flaps are disposed over the edge of a card or sheet 8 and secured thereto by the adhesive or cementitious coating 7. In Figs. 1, 2 and 7, the tab is fitted closely over the edge of the index projection 8 of the card or sheet, and in Figs. 5 and 6,

it is fitte'd'over an edge of the card or sheet so as to project therefrom a slight distance and itself form an indexprojection. A suitable index slip or label 9 is adapted tobe inserted endwise into the open ended pocket formed between the flaps by the double folds, and, when so positioned the index slip or label will be protected against handling and soiling. The slip or label will be provided with suitable index indicia or characterswhich will be visible through the transparent material of which the tab is formed. The index slip or label may be re moved by sliding the same endwise from the pocket, and thus the'index slips or labels can be interchanged or replaced as desired. It will, therefore, be unnecesary to discard the index'sheet or card to which the tab has been applied when it is desired to change the nature of-the index characteristics to be attached thereto. All that is necessary to no effect such a change is'to substitute a new label or slip in the open ended pocket, which names? new label will bear the desired indicia or characters.

In Fig. 7, the index projection 8 of the card and the tab applied thereto are bent backwardly through a small an le so as to more effectively display the labe contained in the pocket of the tab.

The tab may be very inexpensively produced through the double folding of a sheet of transparent material because the folding can be aocomplishedvery inexpensively by folding machines. The tabs may be applied to the index cards or sheets and marketed directly as such, or the tabs may be marketed by themselves and applied by the purchaser to the index elements.

It will be obvious that various changes in the method and in the details and arrangements of parts herein described and illustrated for-the purpose of explaining the nature of the invention may be made by those skilled in the art within the principle and sco of the invention as set forth in the appen ed claims I claim:

1. An index tab comprising a sheet of transparent material folded upon itself to form attaching flaps, the folded sheet being double: back upon itself along a line intermediate the first fold and the edges opposite thereto to form between the folded edges a pocket for receiving and displaying an element with suitable distinguishing characteristics.

2. An index tab comprising a sheet of transparent material having one fold upon itself to form attaching flaps, and a second and common fold intermediate the first fold and the-edges opposite thereto to form between the folded edges a pocket for receiving and displaying an element with suitable distinguishing characteristics, the abutting faces brought together by the second fold being secured together.

3. An index tab comprising a sheet of transparent material having one fold upon itself to form attaching flaps, and a second fold intermediate the first fold and the edges opposite thereto to form between the folded edges a pocket for receiving and displaying an element with suitable distinguishing characteristics, the abutting faces brought together by the second fold being cemented together.

4. An index tab comprising, a sheet of transparent material having one fold upon itself to form attaching flaps, and a second fold intermediate the first fold and the edges opposite thereto to form between the folded edges a pocket for receiving and displaying an element with suitable distinguishing characteristics, and adhesive coatings upon the abutting faces of the flaps between the second fold and the edges opposite thereto whereby the tab may be secured to an index element over an edge thereof.

5. An index card or sheet, and an index tab' secured to an edge of the card or sheet, said tab being made of transparent material with a double fold therein forming an open ended pocket for the reception of an index slip or label, the surfaces of the material brought together by the second fold being secured together.

In witness whereof, I hereunto subscribe my signature.
